SBR法生物后处理喹吖啶酮颜料中间体废水实验研究

Experimental Study on Quinacridinone Pigment-intermediate Wastewater Treatment by SBR Biological behind Treatment

采用SBR法处理喹吖啶酮颜料中间体废水，考察了SBR法处理喹吖啶酮颜料中间体废水的效果、曝气时间、pH值和进水COD值等条件对处理效果的影响。结果表明曝气时间6h、进水pH值为7．0—8．5、进水COD值为1000—2000mg／L时，COD去除率达到71．3％～77．2％。

This paper studied the research work for SBR used to treat Quinacridinone pigment -intermediate wastewater, and the influence on treatment effect by changing aeration time, pH, the COD of input wastewater. The Results showed that under time 6h, the COD of input wastewater 1 000 -2 -77.2%. the experimental condition of pH 7.0 - 8.5, aeration 000mg/L, the removal rate of COD can reach 71.3%
